EV Applications

Truetrac offers high power density in a limited packaging space thanks to its high-strength helical gear design, making it a smart choice for EV applications. It is fully automatic and maintenance-free, and can transfer up to 3.5 times more torque to the high traction wheel. It retains its torque bias retention for a lifetime and does not need electronic connections or software to integrate into a vehicle.

Smooth, automatic operation

The Detroit Truetrac differential operates as a standard or open differential under normal driving conditions, allowing one wheel to spin faster or slower as necessary. When a wheel encounters a loss of traction or the terrain changes, the gear separation forces take effect and transfer torque to the high-traction wheel. The helical-shaped gears mesh with increasing force until wheel spin is slowed or completely stopped. When the vehicle exits the low traction situation, the differential resumes normal operation.
